  • 1/2 through 250 ton actuators.
  • Housings are constructed of a durable aluminum alloy up to 1 ton and ductile iron / steel alloy for higher tonnage linear actuators.
  • Load screws are precision formed of high strength steel to provide optimal performance.
  • Gear nuts are high alloy bronze for exceptional wear and are supported by tapered roller bearing to provide both axial / side support.
Applications vary from processing mills to clean-rooms, automated assembly and food processing. They are used to open, close or position satellite antennas, doors, ladles, gates, dampers, valves, rollers, tables, presses and other types application requiring linear motion control.
